BACKGROUND OF THE INVENTION

Protein kinases are a large multigene family consisting of more than 500 proteins which play a critical role in the development and treatment of a number of human diseases in oncology, neurology and immunology. The Tec kinases are non-receptor tyrosine kinases which consists of five members (Tec (tyrosine kinase expressed in hepatocellular carcinoma), Btk (Bruton's tyrosine kinase), Itk (interleukin-2 (IL-2)-inducible T-cell kinase; also known as Emt or Tsk), Rlk (resting lymphocyte kinase; also known as Txk) and Bmx (bone-marrow tyrosine kinase gene on chromosome X; also known as Etk)) and are primarily expressed in haematopoietic cells, although expression of Bmx and Tec has been detected in endothelial and liver cells. Tec kinases (Itk, Rlk and Tec) are expressed in T cell and are all activated downstream of the T-cell receptor (TCR). Btk is a downstream mediator of B cell receptor (BCR) signaling which is involved in regulating B cell activation, proliferation, and differentiation. More specifically, Btk contains a PH domain that binds phosphatidylinositol (3,4,5)-trisphosphate (PIP3). PIP3 binding induces Btk to phosphorylate phospholipase C (PLCγ), which in turn hydrolyzes PIP2 to produce two secondary messengers, inositol triphosphate (IP3) and diacylglycerol (DAG), which activate protein kinase PKC, which then induces additional B-cell signaling. Mutations that disable Btk enzymatic activity result in XLA syndrome (X-linked agammaglobulinemia), a primary immunodeficiency. Given the critical roles which Tec kinases play in both B-cell and T-cell signaling, Tec kinases are targets of interest for autoimmune disorders.

Consequently, there is a great need in the art for effective inhibitors of Btk. The present invention fulfills these and other needs.

As used herein, the term “pharmaceutically acceptable salt” refers to those salts which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and lower animals without undue toxicity, irritation, allergic response and the like, and are commensurate with a reasonable benefit/risk ratio. Pharmaceutically acceptable salts are well known in the art. For example, S. M. Berge et al., describe pharmaceutically acceptable salts in detail in J. Pharmaceutical Sciences, 1977, 66, 1-19, incorporated herein by reference.

In certain embodiments, the neutral forms of the compounds are regenerated by contacting the salt with a base or acid and isolating the parent compound in the conventional manner. In some embodiments, the parent form of the compound differs from the various salt forms in certain physical properties, such as solubility in polar solvents.

Unless otherwise stated, structures depicted herein are also meant to include all isomeric (e.g., enantiomeric, diastereomeric, and geometric (or conformational)) forms of the structure; for example, the R and S configurations for each asymmetric center, Z and E double bond isomers, and Z and E conformational isomers. Therefore, single stereochemical isomers as well as enantiomeric, diastereomeric, and geometric (or conformational) mixtures of the present compounds are within the scope of the invention. Unless otherwise stated, all tautomeric forms of the compounds of the invention are within the scope of the invention. Additionally, unless otherwise stated, structures depicted herein are also meant to include compounds that differ only in the presence of one or more isotopically enriched atoms. For example, compounds having the present structures including the replacement of hydrogen by deuterium or tritium, or the replacement of a carbon by a ¹³C- or ¹⁴C-enriched carbon are within the scope of this invention. Such compounds are useful, for example, as analytical tools, as probes in biological assays, or as therapeutic agents in accordance with the present invention.

The term “oxo,” as used herein, means an oxygen that is double bonded to a carbon atom, thereby forming a carbonyl.

One of ordinary skill in the art will appreciate that the synthetic methods, as described herein, utilize a variety of protecting groups. By the term “protecting group,” as used herein, it is meant that a particular functional moiety, e.g., O, S, or N, is masked or blocked, permitting, if desired, a reaction to be carried out selectively at another reactive site in a multifunctional compound. Suitable protecting groups are well known in the art and include those described in detail in Protecting Groups in Organic Synthesis, T. W. Greene and P. G. M. Wuts, 3^(rd) edition, John Wiley & Sons, 1999, the entirety of which is incorporated herein by reference.

Assays

To develop useful Tec kinase family inhibitors, candidate inhibitors capable of decreasing Tec kinase family enzymatic activity may be identified in vitro. The activity of the inhibitor compounds can be assayed utilizing methods known in the art and/or those methods presented herein.

Compounds that decrease Tec kinase family members' enzymatic activity may be identified and tested using a biologically active Tec kinase family member, either recombinant or naturally occurring. Tec kinases can be found in native cells, isolated in vitro, or co-expressed or expressed in a cell. Measuring the reduction in the Tec kinase family member enzymatic activity in the presence of an inhibitor relative to the activity in the absence of the inhibitor may be performed using a variety of methods known in the art, such as the POLYGAT-LS assays described below in the Examples. Other methods for assaying the activity of Btk and other Tec kinases are known in the art. The selection of appropriate assay methods is well within the capabilities of those of skill in the art.

Once compounds are identified that are capable of reducing Tec kinase family members' enzymatic activity, the compounds may be further tested for their ability to selectively inhibit a Tec kinase family member relative to other enzymes. Inhibition by a compound of the invention is measured using standard in vitro or in vivo assays such as those well known in the art or as otherwise described herein.

Compounds may be further tested in cell models or animal models for their ability to cause a detectable changes in phenotype related to a Tec kinase family member activity. In addition to cell cultures, animal models may be used to test Tec kinase family member inhibitors for their ability to treat autoimmune disorders, inflammatory disorders, or cancer in an animal model.

Pharmaceutical Compositions

In another aspect, the present invention provides pharmaceutical compositions comprising a compound of formula I or a compound of formula I in combination with a pharmaceutically acceptable excipient (e.g., carrier).

The pharmaceutical compositions include optical isomers, diastereomers, or pharmaceutically acceptable salts of the inhibitors disclosed herein. The compound of formula I included in the pharmaceutical composition may be covalently attached to a carrier moiety, as described above. Alternatively, the compound of formula I included in the pharmaceutical composition is not covalently linked to a carrier moiety.

A “pharmaceutically acceptable carrier,” as used herein refers to pharmaceutical excipients, for example, pharmaceutically, physiologically, acceptable organic or inorganic carrier substances suitable for enteral or parenteral application that do not deleteriously react with the active agent. Suitable pharmaceutically acceptable carriers include water, salt solutions (such as Ringer's solution), alcohols, oils, gelatins, and carbohydrates such as lactose, amylose or starch, fatty acid esters, hydroxymethycellulose, and polyvinyl pyrrolidine. Such preparations can be sterilized and, if desired, mixed with auxiliary agents such as lubricants, preservatives, stabilizers, wetting agents, emulsifiers, salts for influencing osmotic pressure, buffers, coloring, and/or aromatic substances and the like that do not deleteriously react with the compounds of the invention.

The compounds of the invention can be administered alone or can be coadministered to the subject. Coadministration is meant to include simultaneous or sequential administration of the compounds individually or in combination (more than one compound). The preparations can also be combined, when desired, with other active substances (e.g. to reduce metabolic degradation).

Formulations

Compounds of the present invention can be prepared and administered in a wide variety of oral, parenteral, and topical dosage forms. Thus, the compounds of the present invention can be administered by injection (e.g. intravenously, intramuscularly, intracutaneously, subcutaneously, intraduodenally, or intraperitoneally). Also, the compounds described herein can be administered by inhalation, for example, intranasally. Additionally, the compounds of the present invention can be administered transdermally. It is also envisioned that multiple routes of administration (e.g., intramuscular, oral, transdermal) can be used to administer the compounds of the invention. Accordingly, the present invention also provides pharmaceutical compositions comprising a pharmaceutically acceptable carrier or excipient and one or more compounds of the invention.

For preparing pharmaceutical compositions from the compounds of the present invention, pharmaceutically acceptable carriers can be either solid or liquid. Solid form preparations include powders, tablets, pills, capsules, cachets, suppositories, and dispersible granules. A solid carrier can be one or more substance that may also act as diluents, flavoring agents, binders, preservatives, tablet disintegrating agents, or an encapsulating material.

In powders, the carrier is a finely divided solid in a mixture with the finely divided active component. In tablets, the active component is mixed with the carrier having the necessary binding properties in suitable proportions and compacted in the shape and size desired.

The powders and tablets preferably contain from 5% to 70% of the active compound. Suitable carriers are magnesium carbonate, magnesium stearate, talc, sugar, lactose, pectin, dextrin, starch, gelatin, tragacanth, methylcellulose, sodium carboxymethylcellulose, a low melting wax, cocoa butter, and the like. The term “preparation” is intended to include the formulation of the active compound with encapsulating material as a carrier providing a capsule in which the active component with or without other carriers, is surrounded by a carrier, which is thus in association with it. Similarly, cachets and lozenges are included. Tablets, powders, capsules, pills, cachets, and lozenges can be used as solid dosage forms suitable for oral administration.

For preparing suppositories, a low melting wax, such as a mixture of fatty acid glycerides or cocoa butter, is first melted and the active component is dispersed homogeneously therein, as by stirring. The molten homogeneous mixture is then poured into convenient sized molds, allowed to cool, and thereby to solidify.

Liquid form preparations include solutions, suspensions, and emulsions, for example, water or water/propylene glycol solutions. For parenteral injection, liquid preparations can be formulated in solution in aqueous polyethylene glycol solution.

When parenteral application is needed or desired, particularly suitable admixtures for the compounds of the invention are injectable, sterile solutions, preferably oily or aqueous solutions, as well as suspensions, emulsions, or implants, including suppositories. In particular, carriers for parenteral administration include aqueous solutions of dextrose, saline, pure water, ethanol, glycerol, propylene glycol, peanut oil, sesame oil, polyoxyethylene-block polymers, and the like. Ampoules are convenient unit dosages. The compounds of the invention can also be incorporated into liposomes or administered via transdermal pumps or patches. Pharmaceutical admixtures suitable for use in the present invention include those described, for example, in Pharmaceutical Sciences (17th Ed., Mack Pub. Co., Easton, Pa.) and WO 96/05309, the teachings of both of which are hereby incorporated by reference.

Aqueous solutions suitable for oral use can be prepared by dissolving the active component in water and adding suitable colorants, flavors, stabilizers, and thickening agents as desired. Aqueous suspensions suitable for oral use can be made by dispersing the finely divided active component in water with viscous material, such as natural or synthetic gums, resins, methylcellulose, sodium carboxymethylcellulose, and other well-known suspending agents.

Also included are solid form preparations that are intended to be converted, shortly before use, to liquid form preparations for oral administration. Such liquid forms include solutions, suspensions, and emulsions. These preparations may contain, in addition to the active component, colorants, flavors, stabilizers, buffers, artificial and natural sweeteners, dispersants, thickeners, solubilizing agents, and the like.

The pharmaceutical preparation is preferably in unit dosage form. In such form the preparation is subdivided into unit doses containing appropriate quantities of the active component. The unit dosage form can be a packaged preparation, the package containing discrete quantities of preparation, such as packeted tablets, capsules, and powders in vials or ampoules. Also, the unit dosage form can be a capsule, tablet, cachet, or lozenge itself, or it can be the appropriate number of any of these in packaged form.

The quantity of active component in a unit dose preparation may be varied or adjusted from 0.1 mg to 10000 mg, more typically 1.0 mg to 1000 mg, most typically 10 mg to 500 mg, according to the particular application and the potency of the active component. The composition can, if desired, also contain other compatible therapeutic agents.

Some compounds may have limited solubility in water and therefore may require a surfactant or other appropriate co-solvent in the composition. Such co-solvents include: Polysorbate 20, 60, and 80; Pluronic F-68, F-84, and P-103; cyclodextrin; and polyoxyl 35 castor oil. Such co-solvents are typically employed at a level between about 0.01% and about 2% by weight.

Viscosity greater than that of simple aqueous solutions may be desirable to decrease variability in dispensing the formulations, to decrease physical separation of components of a suspension or emulsion of formulation, and/or otherwise to improve the formulation. Such viscosity building agents include, for example, polyvinyl alcohol, polyvinyl pyrrolidone, methyl cellulose, hydroxy propyl methylcellulose, hydroxyethyl cellulose, carboxymethyl cellulose, hydroxy propyl cellulose, chondroitin sulfate and salts thereof, hyaluronic acid and salts thereof, and combinations of the foregoing. Such agents are typically employed at a level between about 0.01% and about 2% by weight.

The compositions of the present invention may additionally include components to provide sustained release and/or comfort. Such components include high molecular weight, anionic mucomimetic polymers, gelling polysaccharides, and finely-divided drug carrier substrates. These components are discussed in greater detail in U.S. Pat. Nos. 4,911,920; 5,403,841; 5,212,162; and 4,861,760. The entire contents of these patents are incorporated herein by reference in their entirety for all purposes.

Effective Dosages

Pharmaceutical compositions provided by the present invention include compositions wherein the active ingredient is contained in a therapeutically effective amount, i.e., in an amount effective to achieve its intended purpose. The actual amount effective for a particular application will depend, inter alia, on the condition being treated. For example, when administered in methods to treat cancer, such compositions will contain an amount of active ingredient effective to achieve the desired result (e.g. decreasing the number of cancer cells in a subject).

The dosage and frequency (single or multiple doses) of compound administered can vary depending upon a variety of factors, including route of administration; size, age, sex, health, body weight, body mass index, and diet of the recipient; nature and extent of symptoms of the disease being treated (e.g., the disease responsive to Btk inhibition); presence of other diseases or other health-related problems; kind of concurrent treatment; and complications from any disease or treatment regimen. Other therapeutic regimens or agents can be used in conjunction with the methods and compounds of the invention.

For any compound described herein, the therapeutically effective amount can be initially determined from cell culture assays. Target concentrations will be those concentrations of active compound(s) that are capable of decreasing kinase enzymatic activity as measured, for example, using the methods described.

Therapeutically effective amounts for use in humans may be determined from animal models. For example, a dose for humans can be formulated to achieve a concentration that has been found to be effective in animals. The dosage in humans can be adjusted by monitoring kinase inhibition and adjusting the dosage upwards or downwards, as described above.

Dosages may be varied depending upon the requirements of the patient and the compound being employed. The dose administered to a patient, in the context of the present invention, should be sufficient to effect a beneficial therapeutic response in the patient over time. The size of the dose also will be determined by the existence, nature, and extent of any adverse side effects. Generally, treatment is initiated with smaller dosages, which are less than the optimum dose of the compound. Thereafter, the dosage is increased by small increments until the optimum effect under circumstances is reached. In some embodiments, the dosage range is 0.001% to 10% w/v. In some embodiments, the dosage range is 0.1% to 5% w/v.

Dosage amounts and intervals can be adjusted individually to provide levels of the administered compound effective for the particular clinical indication being treated. This will provide a therapeutic regimen that is commensurate with the severity of the individual's disease state.

Example 239: Protocol for Human B Cell Stimulation

Human B cells are purified from 150 ml of blood. Briefly, the blood is diluted 1/2 with PBS and centrifuged through a Ficoll density gradient. The B cells are isolated from the mononuclear cells by negative selection using the B cell isolation kit II from Milenyi (Auburn, Calif.). 50,000 B cells per well are then stimulated with 10 ug/ml of goat F(ab′)₂ anti-human IgM antibodies (Jackson ImmunoResearch Laboratories, West Grove, Pa.) in a 96-well plate. Compounds are diluted in DMSO and added to the cells. Final concentration of DMSO is 0.5%. Proliferation is measured after 3 days using Promega CellTiter-Glo (Madison, Wis.).

Compound inhibition is measured after monitoring the amount of phosphorylation of a fluorescein-labeled polyGAT peptide (Invitrogen PV3611) in the presence of active BTK enzyme (Upstate 14-552), ATP, and inhibitor. The BTK kinase reaction was done in a black 96 well plate (costar 3694). For a typical assay, a 24 μL aliquot of a ATP/peptide master mix (final concentration; ATP 10 μM, polyGAT 100 nM) in kinase buffer (10 mM Tris-HCl pH 7.5, 10 mM MgCl₂, 200 μM Na₃PO₄, 5 mM DTT, 0.01% Triton X-100, and 0.2 mg/ml casein) is added to each well. Next, 1 μL of a 4-fold, 40× compound titration in 100% DMSO solvent is added, followed by adding 15 uL of BTK enzyme mix in 1× kinase buffer (with a final concentration of 0.25 nM). The assay is incubated for 30 minutes before being stopped with 28 μL of a 50 mM EDTA solution. Aliquots (5 μL) of the kinase reaction are transferred to a low volume white 384 well plate (Corning 3674), and 5 μL of a 2× detection buffer (Invitrogen PV3574, with 4 nM Tb-PY20 antibody, Invitrogen PV3552) is added. The plate is covered and incubated for 45 minutes at room temperature. Time resolved fluorescence (TRF) on Molecular Devices M5 (332 nm excitation; 488 nm emission; 518 nm fluorescein emission) is measured. IC₅₀ values are calculated using a four parameter fit with 100% enzyme activity determined from the DMSO control and 0% activity from the EDTA control.

Example 241:—In Vitro Inhibition of BTK Activity in Mouse Whole Blood

Anti-rabbit MSD plates (Meso Scale Discovery, Rockville, Md.) are coated with 35 uL/well of rabbit anti-BTK C82B8 (Cell Signaling Technology, Danvers, Mass.) diluted 1:50 in PBS. Plates are incubated for 2 hours±1 hour at room temp, shaking (setting 3-5) or ON at 4° C. Plates are blocked with MSD Blocker A (Meso Scale Discovery, Rockville, Md.) using 3% MSD Blocker A in TBST. Coated plates are first washed 3× with 250 uL/well TBST followed by addition of 200 uL/well 3% Blocker A/TBST. Plates are blocked for >2 hour at RT, shaking or ON at 4° C.

Whole blood is collected from DBA/1 mice in 16×100 sodium heparin tubes (Becton Dickinson, Cat No. 367874). Blood from multiple DBA/1 mice is pooled. 96 uL of whole blood per well is aliquotted into a 96-round bottom plate changing tips each time. 4 uL diluted test compound is added to each sample, mixed, and incubated for 30 min at 37° C.

For serial dilutions of test compound, 1000× plate is produced with serial dilutions of test compound in 100% DMSO. Ten dilutions, done 1:3, starting at 10 mM are created by: adding 15 uL of test compound at 10 mM in 100% DMSO to well A1; adding 10 uL 100% DMSO to wells A2-A12; diluting 5 uL from well A1 to well A2 and mixing; continuing 1:3 serial dilutions, changing tips between transfers, to well A10. Wells A11 and A12 contain 100% DMSO without test compound.

For dilution 1, a 1:40 plate is created. Using a 12-well multi-channel pipette, each concentration of test compound or DMSO is diluted 1:40 by adding 2 uL from each well of 1000× stock plate to 78 uL water and mixing.

For dilution 2, test compound or DMSO are added to whole blood by diluting 1:25. Using a 12-well multi-channel pipette, 4 uL from 1:40 plate (B) is added to 96 uL whole blood and mixed.

The final concentration of test compounds are shown below. The concentration of DMSO is 0.1% final in each well.

Lysing buffer used to lyse whole blood is prepared as follows. A 10× Lysis buffer is prepared using 1500 mM NaCl; 200 mM Tris, pH 7.5; 10 mM EDTA; 10 mM EGTA; and 10% Triton-X-100. The 10× Lysis buffer is diluted to 1× in dH₂O, and complete lysing buffer (+/−phosphatase inhibitors) is prepared as follows:

+PPi (mL) −PPi (mL) 1X Lysis buffer 10 10 500 mM PMSF in DMSO 0.02 0.02 Phosphatase Inhibitor 3 0.1 Phosphatase Inhibitor 2 0.1 Protease Inhibitor (cOmplete) (1 tablet for 10 mL) 1 tablet 1 tablet PhosStop (1 tablet for 10 mL) 1 tablet Sodium Orthovanadate (Na₃VO₄) (50 uM final) 0.1 Sodium Fluoride (NaF) (10 mM final) 0.005 1% Deoxycholate (0.25% final) 2.5 2.5

100 uL of complete lysing buffer (+/−phosphatase inhibitors) is added to each well, and mixed well by pipetting up and down a few times. Wells 1-10 and 12 received 1× Lysis buffer containing phosphatase inhibitors (+PPi) and well 11 receive 1× Lysis buffer without phosphatase inhibitors (−PPi). Samples are incubated for 1 hour on ice or at 4° C. Samples are mixed again at half time point for complete lysing.

Blocking buffer is washed off blocked MSD plates with 250 uL TBST per well 3 times. 100-150 uL of whole blood lysates is added to each well of the coated and blocked MSD plates followed by incubation overnight in a cold room with shaking.

The plates are then washed 4 times with 250 μL TBST per well. Biotinylated phospho-tyrosine mouse mAb (pY100, Cell Signaling Technology, Danvers, Mass.) was diluted 1:125 in 1% Blocker A. Mouse anti-BTK mAb (Fitzgerald Industries International, Acton, Mass.) is diluted 1:900 in 1% Blocker A. 35 μL of diluted pY100 or diluted anti-BTK mAb is added to each well and incubated for 2 hours at room temperature, shaking.

Plates are then washed 3 times with 250 uL TBST/well. 35 uL of 1:500 Streptavidin-Sulfo-Tag labeled antibody in 3% Blocker A is added to each well. For anti-BTK, 35 uL of 1:500 anti-mouse-Tag labeled antibody in 3% Blocker A is added to each well. Plates are incubated for 1 hour at RT, shaking.

To develop and read the plates, IX Read Buffer in dH₂O is prepared from 4× stock. Plates are washed 3 times with 250 uL TBST/well. 150 uL of 1×MSD Read Buffer is added to each well. Plates are read in a SECTOR Imager 6000 (Meso Scale Discovery, Rockville, Md.).

Example 242—PK/PD Correlation in DBA1 Mice

Mice are dosed orally (PO) with test compound in CMC-Tween and killed by CO₂ asphyxiation at various times after dosing. Heparinized whole blood is immediately collected by cardiac puncture and split into two samples. One sample is used to quantify the amount of test compound present and the other is lysed in MSD lysis buffer in the presence of phosphatase inhibitors. Heparinized whole blood from cardiac punctures of vehicle (CMC-Tween) dosed mice are lysed either in the presence (high control) or absence (low control) of phosphatase inhibitors. Lysed whole blood samples are analyzed for phospho-BTK as described above. The percent inhibition of phospho-BTK in each whole blood sample from dosed mice is calculated as follows: (1-((pBTK(x+PPi)−pBTK(vehicle−PPi))/(pBTK(vehicle+PPi))))*100, where pBTK(x+PPi) is the ECL signal for whole blood from each test compound-treated mouse, pBTK(vehicle−PPi) is the average ECL signal of whole blood from vehicle-treated mice lysed in the absence of phosphatase inhibitors (low control) and pBTK(vehicle+PPi) is the average ECL signal of whole blood from vehicle-treated mice lysed in the presence of phosphatase inhibitors (high control).

Example 243: In Vitro PD Assay in Human Whole Blood

Human heparinized venous blood was purchased from Bioreclamation, Inc. or SeraCare Life Sciences and shipped overnight. Whole blood was aliquoted into 96-well plate and “spiked” with serial dilutions of test compound in DMSO or with DMSO without drug. The final concentration of DMSO in all wells was 0.1%. The plate was incubated at 37° C. for 30 min. Lysis buffer containing protease and phosphatase inhibitors was added to the drug-containing samples and one of the DMSO-only samples (+PPi, high control), while lysis buffer containing protease inhibitors was added to the other DMSO-only samples (−PPi, low control). All of the lysed whole blood samples were subjected to the total BTK capture and phosphotyrosine detection method described in Example 241. ECL values were graphed in Prism and a best-fit curve with restrictions on the maximum and minimum defined by the +PPi high and −PPi low controls was used to estimate the test compound concentration that results in 50% inhibition of ECL signal by interpolation.

Table 2 shows the activity of selected compounds of this invention in the pBTK assay, wherein each compound number corresponds to the compound numbering set forth in Examples 1-238 herein, supra. Compounds have an activity designated as “A” provided an IC₅₀<500 nM; compounds having an activity designated as “B” provided an IC₅₀ of 500-1499 nM; compounds having an activity designated as “C” provided an IC₅₀ of 1500-10000 nM.
